The differentiated type of neuroblastomaxglioma hybrid cell line, NG, has widely been used in in vitro studies instead of primary-cultured neurons. Here we examined whether NG cells can be used as a model for studying the neuronal differentiation process. We compared the expression of neuronal proteins neurofilament NF , phosphorylated-NF p-NF , microtubule associated protein 2, synaptophysin, syntaxin 1, choline acetyltransferase, and acetylcholinesterase AChE and a glial protein vimentin between undifferentiated and differentiated NG cells by immunocytochemistry and immunoblot analysis. The expression of all neuronal proteins, with the exception of NF and p-NF, was positive in differentiated cells, but almost negative in undifferentiated cells. On the other hand, cytoskeletal intermediate filaments NF and p-NF for neurons and that vimentin for glia were present in both undifferentiated and differentiated cells. Our results showed that even though the expression of cytoskeletal filaments does not change during differentiation of NG cells, these cells during differentiation can serve as an appropriate tool for investigating and understanding the mechanisms involved in neuronal development and differentiation. Abstract The differentiated type of neuroblastomaxglioma hybrid cell line, NG, has widely been used in in vitro studies instead of primary-cultured neurons.

All cell cultures have the potential to carry as yet unidentified adventitious agents. It is the responsibility of the end user to ensure that their facilities comply with biosafety regulations for their own country. The Culture Collections represent deposits of cultures from world-wide sources. While every effort is made to ensure details distributed by Culture Collections are accurate, Culture Collections cannot be held responsible for any inaccuracies in the data supplied. References where quoted are mainly attributed to the establishment of the cell culture and not for any specific property of the cell line, therefore further references should be obtained regarding cell culture characteristics. Passage numbers where given act only as a guide and Culture Collections does not guarantee the passage number stated will be the passage number received by the customer. Cultures supplied by Culture Collections are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line. Neuroblastoma x glioma hybrid was formed by Sendai virus-induced fusion of the mouse neuroblastoma clone N18TG-2 and the rat glioma clone C6 BV

Glioblastoma is a rapidly progressing brain cancer that is very difficult to treat. Given that many aspects of cell and tissue behavior are controlled by electric signaling, we sought to test whether drugs that target ion channel proteins might be effective at controlling the spread and functionality of glioblastoma cells in culture. Testing aspects of cell growth and physiology, we show that several novel combinations of ion channel drugs, which are already approved in human patients for other purposes, are highly effective against two types of glioblastoma cells.

Testing aspects of cell growth and physiology, we show that several novel combinations of ion channel drugs, which are already approved in human patients for other purposes, are highly effective against two types of glioblastoma cells. This facilitates the development of new strategies to address cancer by repurposing the large class of ion channel drugs against cancer. Glioblastoma is a lethal brain cancer that commonly recurs after tumor resection and chemotherapy treatment. Depolarized resting membrane potentials and an acidic intertumoral extracellular pH have been associated with a proliferative state and drug resistance, suggesting that forced hyperpolarization and disruption of proton pumps in the plasma membrane could be a successful strategy for targeting glioblastoma overgrowth. A subset of these were tested in the U87 human glioblastoma cell line.

In the fundamental process of neuronal path-finding, a growth cone at the tip of every neurite detects and follows multiple guidance cues regulating outgrowth and initiating directional changes. Using fluorescence time lapse microscopy we could identify two distinct modes of growth cone collapse leading either to neurite retraction or to a controlled halt of neurite extension. In the latter case, lateral movement and folding of actin bundles filopodia confine microtubule extension and limit microtubule-based expansion processes without the necessity of a constantly engaged actin turnover machinery. We term this previously unreported second type fold collapse and suggest that it marks an intermediate-term mode of growth regulation closing the gap between full retraction and small scale fluctuations. Neuronal development during embryogenesis as well as regeneration after injury is a highly complex process that requires robust mechanisms on the single-cell level to produce reliable results.

However, this is not the case for the combination of pantoprazole with NS or lamotrigine, which did not have any significant change in resting membrane potential as compared to control in NG cells. We found that pantoprazole alone did not have a significant effect on the cytoplasmic to nuclear ratio of YAP, but when combined with NS or TMZ, it showed a significant decrease indicative of less YAP in the nucleus as compared to the cytoplasm.
